MULTIPLE-TYPE SEED DISPENSING SYSTEM

摘要

A system (64) for dispensing multiple types of seed as a planting apparatus (planter or drill) travels through an agricultural field. The planting apparatus is typically an implement having row units (58) for applying seed to a field as the implement is pulled by a tractor (10). The system (64) includes multiple seed bins configured to store multiple types of seed. Multiple bins can be formed within a seed hopper by a removable dividing wall. A switch assembly selectively discharges seed from one seed bin in response to control signals generated in a manual or an automatic mode. The control signals are generated using an operator input device in manual mode, and using location signals and a prescription type map in automatic mode. Discharged seed is received by a distribution assembly (68) for delivery to the row units (58). The seed selector (72) may include a rotatable drum (76) driven by a variable-rate motor (28).
